I think my Cibola is out of tune. With disc. on zero, sens. on max, and supertuned. I am only getting a quarter at 7" airtest. What depth is anyone else getting with this same setup? I have the original Cibola with the low tone. I heard that Tesoro could change it to a higher pitch. Anyone know how much they charge for this mod? Thanks for any help. Mark L PS: this is with the 8x9 coil
